I looked at their license that you posted. This is a direct copy/paste:

Quote -
Buyer may use the materials in any personal projects or commercial projects, as long as the Seller's work is protected from extraction and none of the items above have been violated.

If you did that, you fulfilled your obligation and the merchant who emailed you is totally and completely out of line and needs to be pointed to the site's license and reported to the site Admins for harassment.

Sorry, my patience where this type of topic wears thin at times, I personally don't see how the people who run the copyright forum have the patience for it. LOL

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
